The term Customer Communications Management originates from market research institutes such as the Gartner Group or Forester Research and was mainly used in English-speaking countries. There it is correctly defined as Customer Communications Management, i.e. with an "s" at the end of Communication, whereas in the D-A-CH region the spelling Customer Communication Management - without an "s" - has become more common.
Irrespective of this, Customer Communications Management in a comprehensive sense is concerned with operating, organizing and improving a company's customer-related communication.
